Chain Loading

[masamune]

I'm finding myself lost in this area. I would truly appreciate your help.

Synopsis

I've finalized the OS's I intend to multiboot, they are Win XP, Open Solaris 10, Suse 11, and Fedora 9. However, I do not know much about Grubs chainload for the MBR. From my understanding, Xp will be written as (hd0,0).

Possible Setup

Would this the be right?

* Open Solaris 10
* root (hd0,1)
* chainloader +1

* Open Suse 11
* root (hd0,2)
* chainloader +1

* Fedora 9
* root (hd0,3)
* chainloader +1

If XP is on the first partition then yes it would be (hd0,0). Here's my bootloader.

default=0
timeout=30
splashimage=(hd0,5)/boot/grub/splash.xpm.gz

	initrd /boot/initrd-2.6.25.6-55.fc9.i686.img
title   Fedora 8 (2.6.25.6-27.fc8)
	root (hd0,4)
	kernel /boot/vmlinuz-2.6.25.6-27.fc8 ro root=LABEL=/ vga=791
	initrd /boot/initrd-2.6.25.6-27.fc8.img

	rootnoverify (hd0,1)

	root (hd0,2)
	chainloader +1

Fedora 9 is handling booting here. Vista is on /dev/sda2 and XP is on /dev/sda3
